Can't communicate with primary dns server?

My laptop won't connect to Internet It keeps saying "Can't communicate with primary dns server (194.168.4.100)" I have ASUS F5 and just got new Internet with virgin ( I'm using Wi-Fi) the computer says it's connected to the wirelss network but is unidentified. My iPhone connects and my iPod connects and my friends laptop works too but min
e doesn't

If you are using windows:

Click start (windows logo, bottom left) and type network connections and press enter.
Then click your wireless network, then right-click it and select properties.
Then highlight "Internet protocol v 4 (TCP/IPv4)" and a properties button will come up - click it.
Put a dot next to "Obtain an ip address automatically" and "Use the following DNS server addresses"
and enter googles dns server addresses 8.8.8.8 & 8.8.4.4
Press OK and Close and re-start the internet connection.

If you're not using windows, sorry I can't help.

A wireless connection to an "unidentified" network means that your laptop has not established a proper connection to your Virgin router. The "Can't communicate… " error message is just a side effect of this. The specific reference to a primary DNS server is a bit odd; could you have set a fixed DNS server some time in the past? If so you need to revert to the "get automatically… " option.

  • Why doesn't my DNS server work? My computer and iphone can't load anything ONLY in my room. If i go downstairs my Wi-Fi works perfectly. I troubleshooted on my computer and it said my DNS server is not responding. What could be the reason for this? And why does it only not work in a certain area?
  • What is the fastest DNS server? I have an iPhone 4 that buffers YouTube videos constantly and I heard that if you change the DNS on the phone the buffering will speed up. What's the fastest open DNS out there?
  • What does DNS stand for and what does it do? Like when you are on your iPhone and you go to connect to a wireless connection. And it says DNS right under router.
